This CPD webinar covers the need for a Circular Economy and describes an ideal one. Legislation and guides relevant to the lighting industry are outlined. Circular Design principles are examined related to luminaire design, materials, manufacturing and ecosystem. As a coda the Circular Economy is put into a wider environmental impact assessment context. Talk by Roger Sexton, Business Development at Stoane Lighting

Within 100 years, we have put more than 1.5 times
the amount of carbon into the atmosphere than was
admitted over the last 4000 years.
Major causes
• Deforestation
• Burning of fossil fuels

5. • The Intergovernmental Panel on Climate Change (IPCC) has used inputs including land use, energy use and
regional differentiated development for computer simulations producing Global Climate Models.
• The latest 2021 (6th) IPCC Assessment Report has compiled the results of multiple runs from over 100 distinct
climate models.
• It shows a series of 5 possible futures known as Shared Socioeconomic Pathways.
Since 1880:
• 1.1°C increase
• Rise in sea level of over 24cm
• 50% decline in Arctic sea ice
‘Climate change is already affecting every
region on Earth, in multiple ways.’
• Extreme weather: heat, drought and
wildfires
• Rising sea levels and river flooding
• Ocean acidification
• Biodiversity loss
• Human health

6. • Fossil fuel subsidies
• Transport
• Coal
• Alternative, renewable or clean energy
• Carbon trading, taxation and offsetting
• The “cap-and-trade” system
• Developing countries

8. Lighting Standards and Legislation
• EcoDesign regulations now and roadmap
• TM66
• TM65
• Complete LCAs

9. ‘As half of total greenhouse gas emissions and more than 90% of biodiversity loss and water
stress come from resource extraction and processing, the European Green Deal launched a
concerted strategy for a climate-neutral, resource-efficient and competitive economy. Scaling
up the circular economy from front-runners to the mainstream economic players will make a
decisive contribution to achieving climate neutrality by 2050 and decoupling economic
growth from resource use, while ensuring the long-term competitiveness of the EU and
leaving no one behind.’
EU Commission Regulation (EU) 2019/2020 of 5 December
2019 (Single Lighting Regulation) lays down ecodesign
requirements for light sources and separate control gear.
Article 4: ‘Manufacturers, importers or authorised
representatives of containing products shall ensure that
light sources and separate control gears can be replaced
with the use of common available tools and without
permanent damage to the containing product, unless a
technical justification related to the functionality of the
containing product is provided in the technical
documentation explaining why the replacement of light
sources and separate control gear is not appropriate.’

12. CIBSE TM65
TM65 assesses the embodied carbon of products in mechanical, electrical and public health (MEP) systems to indicate GWP.

13. C(2021) 9332, EU COMMISSION RECOMMENDATION published on 16.12.2021
‘This Recommendation promotes the use of the Environmental Footprint methods in relevant
policies and schemes related to the measurement and/or communication of the life cycle
environmental performance of all kinds of products, including both goods and services, and of
organisations.’

14. Good Practice Testimonials
• Becoming a Carbon Neutral Company (Earthly)
• Product Design (ZTA; TM66)
• ReNew with Carbon Calculations (Murrayfield Church)

15. Becoming Carbon Neutral

16. Recycling Materials

17. Pendants made from recycled aluminium and powder coat

18. LED Lifetime

19. Design of repairable and re-manufacturable luminaires.
• Easy access to and replacement of components that are
predicted to fail during the life of the luminaire
• Product designs ease the use of alternate or upgraded parts.
• Extra fixing holes to facilitate subsequent use of different
component types
• Ample leeway mechanically
• Ample leeway thermally

Making Repairs and Remanufactures Happen: On-site Upgrades

24. Issues:
• Lit effect from CMH and 5 incandescent lamps
• Energy saving
• Maintenance
Solution:
• Replace CMH and incandescents to a LED solution. 7 x LED
retrofits (peripheral and central) in shades.
• Use new or ReNew? Considerations:
• Costs. Assume onsite costs of renewing and installing
new are the same but new chandeliers would cost more
• Heritage – retaining original work
• Warranties
• Carbon audit
(Many assumptions in what follows….)

27. New
10 x 305kgCO2e = 3050 KgCO2e
ReNew
10 x 101kgCO2e = 1010 KgCO2e
The saving by choosing to ReNew was
2,040 kgCO2e.
To put this figure into context, this equates to
carbon sequestered by 33.7 tree seedlings
grown for 10 years.
